甘蔗新品种川蔗19号的选育

Breeding of new sugarcane variety chuanzhe 19

川蔗１９ 号是以川糖６１ － ３８０ 为母本与父本川蔗４ 号在海南配制杂交组合选育而成。经多年多点试验结果表明：蔗茎产量４１ 点次新植和宿根蔗平均为８０３１０ ｋｇ／ｈｍ２ ，与对照（ 川蔗１０ 号，下同） 比增产１２ ．９３ ％ ；甘蔗蔗糖分８０ 次检糖（１１ ～１２ 月） 平均为１３ ．４９ ％ ，比对照提高０．０４％ （ 绝对值） ；含糖量４１ 点次平均为１０８４５ｋｇ／ｈｍ２ ，比对照提高１３ ．３２ ％ 。该品种为早熟、高产稳产、蔗茎均匀、宿根性较好、抗性强，适应性广、耐肥抗倒伏优良品种，适宜在四川省的内江、重庆。

Chuanzhe 19 was bred by our institute from the crossing Chuantang 61 380 (female) ×Chuanzhe 4(male) which crossed by Hainan Sugarcane Breeding Station.The testing results of multilocation in many years have shown that the output of cane yield (stalk) 80310 kg/ha in 41 locations it was higher 12.93% than CK (Chuanzhe 10, same in the followings), sugar content in sugarcane in 80 tests (from Nov.to Dec.) was 13.49%,higher 0.04%(absolute) than CK,and sugar yield (mean)in 41 locations was 10845 kg/ha , which higher 13.32% than CK.This variety is an early-maturity, stable and high yield,uniform stalk,good ratoon and suitable for different ecotypes and can planting in Neijiang,Congqing, Panxi etc.
